The geometry of adsorbed C 60 influences its collective properties. We report the first
dynamical low-energy electron diffraction study to determine the geometry of a C 60 …

In nanoscale metal wires, electrical current can cause structural changes through
electromigration, in which the momentum of electrons biases atomic motion, but the …

The temperature dependence of the step line tension on the Si (111)(1× 1) surface is
determined from a capillary wave analysis of two-dimensional island edge fluctuations and …

We report on a surface phase of the Co-vicinal-Cu (111) system which exhibits self-
assembled uniform Co quantum wires that are stable at 300 K. Scanning tunneling …

By adding nanotwins to Cu, the surface electromigration (EM) slows down. The atomic
mobility of the surface step-edges is retarded by the triple points where a twin meets a free …

Silver nanowires fabricated using a wet-chemical synthesis have been characterized in UHV
using scanning tunneling microscopy. The nanowires have a faceted structure with a high …

The shape evolution of two-dimensional islands under electromigration-driven periphery
diffusion is studied by kinetic Monte Carlo (KMC) simulations and continuum theory. The …

Spurred by recent theoretical predictions [Phys. Rev. E 69, 035102 (R)(2004) PLEEE8 1063-
651X 10.1103/PhysRevE. 69.035102; Surf. Sci. Lett. 598, L355 (2005) SUSCAS 0039-6028 …

The decoration of hexagonal Ag/Ag (111) monolayer islands by chains of C 60, observed via
STM at 300 K, dramatically changes the nanocrystalline shape and fluctuations of the …

Small amounts of impurities are known to have remarkably great influence on surface
morphology. We discuss three examples that arise in our research. First, we consider …
